Add a warning about a Hyper-V entry?

I’m using Hyper-V manager in order to list of groups of virtual machines, as you can see:

The first three entries are innocent, but the last one contains a list of VPNs, connecting to virtual machines, present at customers, so I must be really careful not to mess those ones up.

Is there a way to show this? I’m thinking of:

  • Altering the name (like “…VPN01_Customers”)
  • Adding a separator between the first three and the fourth one.
